2. All the answers must be correctly numbered as in the question paper and written

in the answer sheet.

3. Attempt all questions before going on the next section.

4. Read each question carefully and follow the instructions.

SECTION – A READING 15 Marks

1 .Read the following passage carefully : ( 8 marks )

DENUDATION

1 . Denudation of the earth‘s surface is performed by natural processes ---- weathering

, erosion and transport .

2 . Weathering is the process by which rocks are changed or broken up. Rocks

consist of minerals which are affected by gases in the air and by moisture. Some

such chemicals may be oxidized by contact with moist air. Clay , for example , in

contact with the air changes in colour from bluish to brown. Atmospheric air

contains about 0 . 4 % of carbon dioxide , which is dissolved by rain and deposited

on the surface of the earth in the form of weak acid, which gradually converts

calcium carbonate , of which limestone is composed into calcium bicarbonate, often

found in drinking water. Some water is so full of calcium carbonate that when it

drps from the roofs of caves , the deposits form stalactites and stalagmites.

3 . Permeable rocks contain all sorts of soluble materials , and these are dissolved by

rainwater ; these materials are principally salts of sodium , potassium , magnesium

and iron. When these dissolve , permeable rocks are weakened and more exposed

to the effects of other natural agencies , such as wind , rain , sun , frost and ice .

Rocks expand and contract under the intermittent effects of heat and cold and this

expansion and contraction produces cracks and breaches which gradually break

the rocks down.

4 . Sand and grit carried by wind also contribute to weathering by earing away the

softer strata of rocks , often causing the harder layers of rock above to collapse.

5. Rain, running water , waves and moving ice are the principal natural agents of erosion

. Coastal erosion is caused by the action of the waves of the sea, throwing tons of

water with enormous force against shores and cliffs ; the stones and pebbles

present in the water contribute to the erosive action of the water itself. The soil and

minerals loosened and dissolved by this marine action are carried away by the

waves.

~ 40 ~


6 . Moving ice in the form of glaciers carries with it rocks and stones of all sizes

which wear away the ground beneath , leveling and rounding the hills and carryingaway

any soft materials.

7 . Wind , rain , waves and ice all contribute to the process of erosion , and the

fragments are carried away by transporting forces--- streams , rivers and marine

currents. These forces through the centuries have been responsible for depositing in

the sea. Where so far no use can be made of it, an incalculable amount of the

fertile soil of the earth‘s surface , so vital for human existence goes waste.

8. some animals contribute to the process of transportation . worms, for example ,

deposit on the earth‘s surface quantities of subsoil in the form of very fine dust which

is easily washed or blown away.

a. On the basis of your reading of the passage , answer the following questions

briefly : ( 4 marks )

i. What do you mean by weathering ?
